Operating instructions

Giacomini R279D is three-way diverting valve designed for use in HVAC systems. It is operated by an actuator controlled by a thermostat or a clock, allowing for the automatic deviation of heating fluid when there are multiple sources of heat generation. This makes it ideal for systems where it is necessary to control the flow of heating fluid to different zones or rooms. Here is a brief overview of its features and capabilities:

  • Three-way operation: The valve has three ports: one inlet and two outlet ports. This allows it to divert the flow of fluid between two different outlets, depending on the position of the valve.

Descrizione
Le valvole deviatrici R279D sono dispositivi di intercettazione del uido
termovettore che, azionati da un attuatore comandato da un termostato o da
un orologio, permettono la deviazione automatica del uido negli impianti di
climatizzazione. Le valvole deviat rici sono ideali per l’utilizzo in impianti dove
sono presenti più fonti di generazione di calore.

R279D
Description
R279D diverting valves are devices for intercepting the heating fluid which,
triggered by an actuator controlled by a thermostat or by a clock, allow for the
automatic deviation of the fluid in HVAC systems.
Diverting valves are ideal for use in systems where multiple sources of heat
generation are present.
